UNITED STATES a WILFBED Burnt, or WORCESTER, MASSACHUSETTS.

,DUSTPAN.

To all who hi mayconcern:'

Be it known that I, WILFRED Dnrnii, a

' citizen of the United States of America, and

a resident of the city of Worcester, 1n the county of Worcester and'State of Massa-' chusetts, have invented new and useful Improvements in Dustpans, of which the following is a Specification.

1 tact with the floor.

Another object of my invention is to provide a'simple, inexpensive and highly efficient device of this character wherein the cover plate is so arranged and mounted as to normally, when the dust pan is lifted from the floor, close thus preventing the dust in the pan from spreading about the room and becoming infectious to the operator of the dust pan, the arrangement and action of the parts being such that the moment" the dust pan is brought into engagement with the floor or other surface the lidwill automatically fly open thus allowing theoperator to sweep dust therein.

A still further objectof my invention consists inthe provision of ansimple and in-.

stantaneous operating attachment toa dust pan that enables the lid of the dust pan to be controlled by a trigger carried by this lid, this trigger acting as a means for opening the lid when the trigger is depressed and of closing this same lid through gravity when the trigger is free to fall as will happen when the dust pan is lifted out of contact with the floor.

With the above and other objects in view my invention consists in the combination, arrangement and details of construction disclosed in the drawings and specification, and thenmore' particularly pointed out in the appended claims.

In the drawings wherein similar reference characters designate similar parts throughout the respective views thereof,

Figure 1 is a front elevation of the dust pan equipped with my improvement, the lid being shown in open position,

Fig. '3' is a front'elevation of my device showing the lid in closed position, Fig. a'is a side'elevation of Fig. 3, p V

Fig. 5 is a top plan view of the dust pan,

Fig. '6 is. a bottomplan view of the dust pan, and

Fig. 7 is a fragmental sectional elevation of a part of my invention showing the attachment of handle to dust pan.

Referring to the drawings which are merely illustrative of my invention 1 designates the dust pan which may be of any suit,- abledesign and construction but is preferably of the shape shown in the present drawings. The dust pan is open at its front portion as is indicated at 9, and the front edges of the sides of this pan are inclined as at '2 and'slope upwardly, the bottom edges 3 pan. The top portion of thepan is'designated 7 and is also preferably-fiat The side walls A and B of the dust pan preferably incline in'oppositedirections as clearly illus- I trated in Fig. 5. The lid 6 is formed at its opposite ends and at its inner plane with the' lugs 10 formed at right angles thereto and in parallel relation to each other, th'ese lugs being suitably perforated to receive the I pins 11 which are formed or bent upon a substantially. U-shaped member or bail, the pins 11 being particularly formed upon the side arms 12-0f this bail which are suitably guided for vertical movement in the guide .95; lugs 14 also formed outstanding upon the j inclined lower edges 3 of the dust pan, the bottom cross-piece of this U-shaped member or bail being designated 15 and extending longitudinally under the dust pan 1. If desired the upstanding terminal 13 may be formed upon the pins 11 and are adapted with the pins 11 to provide abutments for the lid 6 to rest against when the latter reaches upright open position, and when in this position the abutments assure that the lid will be under the influence of gravity the -moment the dust pan is lifted out of contact with the floor in a manner to be de- It will be noticed that the U-shaped bail or member is guided in a vertical plane and is suspended upon the lid and owing to its weight the lid is held in closed positionas soon as it rests upon the inclined edges 2 of the dust pan. 6

It will now be seen that the pull exerted I by the u -shaped member or trigger 15 is such as to force the lid or cover plate downwardly upon its seat, as long as the tread 15 of this member isout of contact with the floor surface. In the act of using the dust pan the operator forces the tread 15 of the trigger member or bail down in contact with the floor andwhen this is done the dust pan moves down relatively to the bail and this makes the upper ends of the bail move up wardly above the lower end of the dust pan and in doing so the pins 11 will force the lugs 10 of the cover plateupwardly serving as crank and thereupon the lid 6 will move upwardly as far back as the pins 11 permit and the correct position of the lid when upraised is shown in Fig. 2, it being noticed that as long as the dust pan rests upon the floor the trigger tread 15 also rests upon the floor and the lid is in full wide open position and the operator may then sweep in the dust.

into the pan the same as is now done in connection with any pan. The moment it is d6SlI'd to lift thedust pan and place it in providing a resilient spreadable portion for sunk into the bottom of the'dust pan.

another position the pan when lifted allows the weight of the bail and cover plate or lid to act and the cover plate will then close keeping the .dust from coming out of the pan and thus enhancing the sanitary feature of this device.

I design to secure the handle 16 in position as follows: I form a depending tube 22 which is slit throughout its diameter thus taking a good bite or hold upon handles of various diameters. The handle fits this tube projecting downwardly into the dust pan and rests on top of thefcountersunk portion 20 into whose recess 19 the head of a fastener 21 projects, this fastener being a" screw which is then tapped directly into the bottom of the handle 16 and binds this handle down tight upon the portion'20 counter- This handle thus is made to standout vertically from the bottom of thedust pan and is re movable by simply removing the screw or Other fastener. Numerous changes in deprinciple from the details of construction herein disclosed.

f What I desire to claim and 'te'r Patent is member straddling said dust pan, and guides for said side arms upon the sides of said pan, said cross-rod adapted to be moved upprotect by Let- 1 I sign maybe made" without departing in V wardly in order to cause said cover plate to be thrust to open position.

2. A deviceas described consisting of a dust pan having .itsfront end open, a cover plate hingedly, mounted upon, said dust pan so as to normally close {said open front, l

formed at right angles of'said plate ato'pposite ends, a handle secured to said dust pan,

a U shapedbail'trunnioned in said lugs and .7

having its cross-piece projecting movably beneath saiddust pan, said cover upon the depression of said bail adapted to fly open, and stops for limiting the movement to open position of said coverpl'ate for holding it under 'the'influence of gravity. i r

3. A device as described consistingof a dust pan'having an open front, a lid hingedly connected to said dustpan anda dapt ed to close said open front,lugs on said lid at opposite ends, a UTshaped bail straddling said pan'and projecting below said pan when the lid isvclosed, cranks upon said bail trunnioned' in said lugs, and guide lugs for guiding the vertical movement of said'side arm of said bail. a

In witness whereof I have hereunto set myhand and affixed my sealthis 26th day of June, 1920. V v I WILFRED 'DUPRE. [L. s.]
